SUGGESTED HANDLING & CURING: Material is ready to use as received. Store at low temperature to maintain
consistent flow properties. Allow material to warm up to room temperature before opening container. Cure for two
(2) hours at 150°C (Note: best properties are obtained when cured at 121°C for four hours).
STORAGE: Shelf Life: 12 months at 0°C; or 6 weeks at 25°C; or 1 week at 40°C. .
SAFETY & HANDLING: Use with adequate ventilation. Keep away from sparks and open flames. Avoid prolonged
contact with skin and breathing of vapors. Wash with soap and water to remove from skin.
